VALVE.

Specification of Letters Patent.

Pettemtedlllee.. 3(6), 1919.

Application filed March 4, 1919. Serial No. 280,599.

.To all whom t may concern Be it known that I, JOSEPH A. ZENGEL, a citizen of the United States, residing at 1nglewood, in the county of King and State of Tashingtom have invented certain new and useful Improvements in Valves, of which the following is a specification.

This invention relates to an improvement in valves of that type having independent inlets and a common outlet, to thereby mingle or mix thc fluids from the inlet prior to their delivery from the outlet.

The invention is directed to means for controlling the valves of the inlets soy that their operation maybe relatively adjusted to admit varying quantities of the respective fluids at will; the said means permitting control of the volume of the fluids.

lln the drawings v Figure 1 is a vertical section through 'the improved valve.

Fig. 2 is a horizontal section of the same, on the line 2-2, Fig. 1.

'n the drawing, 1 represents a valve casing, here shown as having but tWo inlets 2 and 3, and a centrally enlarged chamber 4, in lvvhich the incoming fluids are mixed, which chamber communicates With a single outlet 5, preferably controlled by a hand valve, as 6.

Valve seats 7 and 8 are provided at the f fluid to said chamber from the inlets. The valves have stems, as 11 and 12, and these are conveniently controlled by springs 13, in any approved manner to bias the valves toward closed position.

Fixed in the chamber 4, preferably threaded into the Wall thereof, is a rod 14, which extends at right angles to the stems `11 and 12 of the inlet valves. A valve operating means is slidably and rotatably mounted on such rod 14, said means being here shown as a body 15 of truncated cone shape and mounted eccentrically on the rod.

An operating rod 16 is connected to the upper and smaller end of the body 15, said rod 16 projecting though a gland*V protected opening 17 in the chamber Wall, so that the' rod 16, which is preferably provided with a handle 18, may be rotated and also moved longitudinally, to communicate similar movements to the body 159 The valve stems 11 and 12 of the inlet valves normally bear on the surface of the body 15, which surface at its minimum projection from the rod 14, will hold the particular valve slightly open. Owing to the eccentric mounting of the body, it is apparent that the same may be rotated to vary the relative opening of the valves 9 and 10, and thus vary the relative quantities of the admitted fluids. Furthermore the volume of admitted fluids may be simultaneously changed, through longitudinal movement of the body 15, by appropriate movement of the operating rod, as Will be evident. rlhis action results from the conical shape of the body.

The casing thus forms in a unitary structure the enlarged `mixing chamber 4, the pair of branches 4', provided With reduced threaded nipples 4", Which receive the threaded end 3', of the supply pipes 2 and 3, having the cross stripsA- 13', against which bears one end of the springs 13, Whose other ends rest against the valve stems 11 and 12, guided in the plates 10 formed With Water inlet openings 10X, all as most clearly shown in Fig. 1.

Of course the body may be arranged to permit the. inlet valves to entirely close, thereby utilizing the body as a cut off, but the present arrangement is preferred.

Claim:

. rlhe valve herein shown and described, consisting of a casing havin an enlarged central chamber, oppositely disposed inlets,

' each formed with a valve seat and a reduced other ends of said springs bear, and a manually controlled valve operating element having'a rotary and sliding movement and arranged in the enlarged chamberto engage and move the stems of said valves,

In testimony whereof l atxmy signature.
